Yep, I must agree with all of that, anyone that thinks their simming would prepare them to fly even the simplest of planes would be in for a big shock.
Everyone has their own ideas of where the Sims fall down, for me it's a matter of vision and perspective from the pilot's seat to the terrain. I know how to use all the views available but often find having made a turn to line up that something has gone wrong along the way that wouldn't have if you actually been sitting in the seat with the ability to use your peripheral vision.
Having said that, what do you expect from that price ?
